This visualization shows the population of the ten most populous countries as circles arranged on a chart, with country names on the y-axis and population values on the x-axis. It uses D3 v5’s `scaleLinear` for the horizontal axis and `scalePoint` for the vertical layout, while `axisBottom` and `axisLeft` render gridlines and ticks. Population data from a CSV file is parsed and multiplied by 1,000, with circles styled orange and labeled via `format('.3s')` to abbreviate values in billions.
